Eyes?

We all know that we can put them there but why?
do the eyes in spore have any real purpose any function?
can my creature just be eyeless and blind like a bat?
or are eyes just there to look good?
i know this is kind of weird to ask
but i just so BORED!

WTF do you think the eyes are there fore? It's game for creating many creatures. You got a point but at first glance the Q looks so obviouse, like the "what does the speed hack do" in Unreal board. Sorry again.
